A really good desert course will be a lot different than a really good wooded course. A person that likes to launch huge hyzer bombs will love the well designed desert course, but may not appreciate a short, but very technical course in the woods. A person that throws very accurate shots within 250 feet would very likely have the opposite opinion.

could easily get much different reviews from average disc golfers because of their skill set. Both are good courses that I'd like to play. There are a lot of people that would not like one or the other.
The best courses will require everything in your arsenal. Technical control, and long bombs.
